关于RK3288_M180_红外输入_投币输入IO使用说明

1st 硬件接法

固件默认为两个GPIO中断输入，M180, ph2.0座子_J38, SPIDI,SPIDO 两个引脚_中断输入(开机默认为0V,外部上拉3.3V(不能超过3.3V否则烧RK3288) 为中断触发！！硬件触发方式为稳定的“上升沿触发 ”__|￣￣ " )，SPICLK,SPICSN 两个引脚_GPIO输出_开机默认为0V

2st 软件APP调用中断,DEMO 代码

    public void DisplayToast(String str)    {        Toast.makeText(this, str, Toast.LENGTH_SHORT).show();    }        //for test EINT    public boolean onKeyDown(int keyCode, KeyEvent event){        switch (keyCode)        {            case KeyEvent.KEYCODE_TV_INPUT_COMPONENT_1:  //for KEY_GINTA                //DisplayToast("RK3288_外部中断_SP1DI,EINT1");            Log.e(MainActivity.ACTIVITY_TAG, "RK3288_外部中断_SP1DI,EINT1..............");                 break;            case KeyEvent.KEYCODE_TV_INPUT_COMPONENT_2:  //for KEY_GINTB            //DisplayToast("RK3288_外部中断_SP1DO,EINT2");            Log.e(MainActivity.ACTIVITY_TAG, "RK3288_外部中断_SP1DO,EINT2..............");                break;                        default:                break;        }        return super.onKeyDown(keyCode, event);    }
